EMPTYING APPARATUS FOR CLAY-BIINS.

No. 812,230. Specification of Letters Patent. Patented Feb. 13, 1906.

Application filed April 6, 1905. Serial No. 254 147.

To all whom it may concern:

Be it known that I, CHARLES W. RAYMOND, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Emptying Apparatus forClay-Bins and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

This invention relates to improvements in apparatus for emptyingstorage-bins.

The apparatus is shown herein in connection with a clay-bin; but it willbe understood that it is suitable for application with any storage-bin.

One of the chief difiiculties met with by brick-makers or clay-workersis in obtaining a satisfactory and uniform feed of clay to the press orpug-mill.

It is therefore the object ofthis invention to overcome this trouble byproviding an automatically-emptying apparatus, which is illustrated inthe accompanying drawings.

In the accompanying drawings, Figure 1 is a side elevation of aclay-bin, showing my emptying apparatus applied. Fig. 2 is a Fig. 3 is atop plan view of the front end of the same. Figs. 4 and 5 are detailviews of the feed-chain; Figs. 6 and 7, detached views of the travelingyoke on the front end of the feed-chain. Fig. 8 is a detail view of theclutch mechanism by means of which the lateral movements of thefeed-chain are reversed. Fig. 9 is a detail view of the'rear shaft ofthe feedchain.

In a detail description of the invention similar reference charactersindicate corresponding parts. The bin 1 is mounted upon a suitablefoundation 2 and consists of a rectangular framework with a floor orbottom 3. The feedchain 4, as shown in Figs. 4 and 5, is of specialconstruction, each alternate link being provided withoutwardly-extending wings 5, which move over the bottom 3 of the binbeneath the clay or material and remove the same as the said chainrevolves and moves laterally over the bottom of the bin.

The mounting of the feed-chain 4 and its operation are as follows: Therear shaft 6 is suitably mounted in bearings 9 at one end of themachine. This shaft carries a sliding sprocket-wheel 7, which is movablelengthwise on the shaft to an extent approximately the width of thefloor of the bin. shaft 8 is suitably mounted in bearings 10 at thefront end of the machine, and upon this shaft is slidingly mounted asecond sprocketwheel 11, simllar to the mountin of the rearwardsprocket-wheel 7. The feed-chain 4 passes over these sprocket-wheels 7and 11. The shaft 8 is a driving-shaft, receiving constant motion frombelt-pulley 12 through pinion 13 and spur-wheel 14, the latter being onthe shaft. The feed-chain is thus constantly rotated during the emptyingoperation. The front sprocket-wheel 11 is moved back and forth along theshaft 8 in order to impart to the feed-chain lateral movements to sweepthe bottom of the bin while said chain is revolving.

15 designates a yoke which loosely incloses the hub 16 of thesprocket-wheel 11 and has a screw-threaded engagement with the hori-Zontal screw-shaft 17. The screw-shaft is mounted in bearings 18 in theforward end of the bin, and on one end of said shaft there is a clutchconsisting of three members 19,, 20, and 21, the middle member 19 beingmovable on the shaft by a shifter-fork 22 to engage it with eitherclutch member 20 or 21 to impart reverse movements to said screw-shaft17. The hubs 20 and 21 of the clutch members carry pulleys 23 and 24,which are belted to the source of power. The belt on pulley 23 is across-belt, so that it may have a reverse movement from belt 24.

The clutch mechanism is engaged to re verse the travel of the shaft 17and yoke 15 by the following mechanism: 25 designates a shifting leverwhich is pivoted to a sill at 26 and carries a weight 27 at its upperend to maintain it in either of the extreme positions shown in full anddotted lines in Fig. 2. 28 is a short link-lever which is pivoted at 29in line with the pivot 26 and has connected to its upper end ahorizontallink-lever 30, which is pivoted at its other end to the shifting lever25. Connected to opposite points of the link-lever 30 are horizontalarms 31 and 32, which occupy positions approximately in line with theextreme sides of the bin in order that when the yoke 15 of the feedchainhas nearly reached the limit of its movement on either side one-or theother of these arms 31 The front.

or 32 is tripped or en aged by said yoke and 1s thereby caused to t 0wthe shifting lever 25 to an opposite position and to reverse theReferring to Fig. 8, it will be seen that the shifting lever 25 moves inan elongated slot 33 in shifting rod 34. The shifting rod 34 isslidingly mounted in bearings 35, and rigidly secured thereto is theshifter-fork 22, before referred to. The length of the slot 33 is lessthan the length of movement of the shifting lever 25 at the point wheresaid shifting rod passes through said slot, or, in other words, thelength of the slot 33 is shorter than the throw of the shifting rod atthat point. This is necessary in "order that the shifting lever 25 mayengage either extreme end of the slot 33 in order to impart thenecessary movement to the shifter-fork 22, The feedchain, it will thusbe seen, while revolving throughout the depth of the bin is at the sametime moving laterally by this reversing mechanism. The lateral movementimparted to the front endof the chain through the yoke 15 will have theeffect of imparting similar movement to the rear sprocket-wheel 7through the chain, so that the entire body of the chain is caused tomove laterally or at right angles to the plane of it's revolution. Theclay or; other material removed from the bin is deliv- 1 ered by thefeed-chain onto a belt conveyor 36-, which passes around a wide-facepulleys 37 and over rollers 38 to the pug-mill or other place ofdelivery. (Not shown.)

Having described invention, I claim 1. In an emptying apparatus forstoragebins, a feed chain or carrier revolving over the floor of thebin, means for imparting lateral movement to said feed-chain during itsrevolvingmovement, and automatic means for reversing the lateralmovements during the revolving movement. 7 In an em tying apparatus forbins, a feed-chain revo ving over the floor of the bin,sliding-sprocket-whe'els upon which said feedchain is mounted, a yokeengaging one of said sprocket-wheels, a screw-shaft upon which the saidyoke is mounted, and means 1 for reversing the direction of rotation ofthe serew -shait to reverse the lateral movements of the feed-chain,through the yoke.
